They might be really shocked at first. The RWBY characters are from a different universe, and the Transformers are huge mechanical beings. Ruby, with her innocent nature, would probably be in awe of the Transformers' power and size.
The cultural clash is also interesting. The Transformers, being from a different kind of universe, have different values and ways of doing things compared to the RWBY characters. This clash and how they resolve it is a great aspect of these fanfics. For example, the Autobots' sense of justice might interact in unexpected ways with RWBY's concept of heroism.
Sure. In RWBY fanfiction, one could imagine a scenario where the concept of Transformers, especially the character Bumblebee if we're referring to the Autobot, is integrated. For example, the technology or the robotic nature of Transformers could be a part of the world - building in the RWBY universe. Maybe the Dust in RWBY could have some connection to the Energon in the Transformers universe, and Bumblebee could be a unique entity that combines the features of both universes, like having a RWBY - style weapon system along with his Autobot abilities.
Friendship is also a big theme. Often, Bumblebee forms strong bonds with the RWBY characters, like Ruby or Yang. They rely on each other in battles and in understanding their respective worlds better. In some fanfics, Bumblebee's loyalty and courage inspire the RWBY team, and vice versa.
One great example could be those that explore crossovers where the Autobots and the characters from RWBY team up to fight a common enemy. For instance, a story might have Optimus Prime and Ruby Rose leading their respective groups in a battle against a powerful new Grimm that has been enhanced by Cybertronian technology.
A lot of RWBY Transformers Prime fanfictions explore the idea of the Transformers being in Remnant. In some, they are seen as gods by the people of Remnant at first. This creates interesting dynamics as the RWBY characters have to figure out if they can trust these new, powerful beings. These fanfictions often delve into themes of trust, power, and friendship.
One common theme is the clash of different cultures. The high - tech, mechanical world of the Transformers and the more magic - based, diverse world of RWBY often lead to interesting cultural exchanges. Another theme is teamwork. Characters from both universes have to learn to work together to face threats. For example, the Autobots and the Huntsmen might combine their strengths to defeat a powerful enemy.
It could start with confusion as the RWBY characters try to understand the world of Transformers. Then they might start to compare and contrast their own abilities with those of the Transformers.
Another interesting fanfic is 'The Transformers of RWBY World'. It delves into how the Transformers would adapt to the RWBY world and how they would interact with the local characters. It has a unique take on the crossover concept.
The technology from the Transformers universe would likely have a huge impact on Remnant. The RWBY characters would be amazed by the Autobots' ability to transform and their powerful weapons. The Autobots, in turn, might be intrigued by the concept of Aura and Semblances.
